摘要

Optimal foraging theory predicts that individuals should resort to kleptoparasitizing food when the net energy obtained from this behavior is greater than that gained form searching for food conventionally. We studied kelptoparasitism in the Cattle Egret (Bubulcus ibis) in southwestern Spain. Intraspecific kelptoparasitism in cattle Egrets was rare. We recorded this behavior only when egrets foraged in large flocks and when potential victims had captured large prey items. In addition, we observed kleptoparasitism in feeding areas with high food availability.
